ATTACHMENT FOR LOADERS.

Application filed June .2, 1925.

To 03N u/zom it 72mg/ concern:

.lle it known that l, Pirrnron H. JOHNSON, a citizen of the ll. ited States, residine at Vale, in the county of Malheur and State of Oregon. have invented certain new and use ful. Improvements in Attachments for lioaders, of which the following is a specification.

The present invention relates to an attachment for loaders particularly of the .Fresno type.

An object of the invention is to provide an attachment, whereby the motor will operate efliciently on diflicult ground, where there is loose rock and roots and where it is almost impossible to load the ordinary Fresno loader.

Another important object of the present .invention is to provide means whereby the scraper is held positively in a loadingposition, and thus is prevented from dumping.

Anotl'ier object of the invention is to provide an attachment of this nature which may be released, so that the loader may be dumped in the usual manner.

Another object of the invention is to provide an attachment whereby the operatingij position of the loader may be varied.

A still further object of the invention is to provide an attachment of this nature, which is exceedingly simple in construction, may be easily applied to the structure of the loader, and may be strong, durable, inem pensive to manufacture, not liable to get easily out of order and otherwise well adapted for the purpose for which it is designed.

llVith the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

ln the drawing:

Figure 1 is a safe elevation of a loader, with my improved attachment thereon.

Figure 2 is a top plan view thereof, and

Figure 8 is a detail perspective view of the shoe.

Referring,r to the drawing in detail, it will be seen that the loader illustrated is of the well-known Fresno type, and includes the scoop A having: the handle B extending;` therefrom and the rocker frames C on the ends thereof. A brace D is disposed between the rear upper edge of the scoop A and the Serial No. 34,397.

intermediate portion of the handles B. Links l@ are ittached to the interior of the scoop A at i" and to clevises on the draft bar H. rlhe parts thus far described are of conventional coi'istriiction, and have been illustrated to demons.y the utility of the attachment. An inverted tlshaped frame, indicated generally by the letter l includes an intermediate cross har 5, eX- tended transversely above the scoop A, and connected Ato arms G in any suitable manner, which are pivoted to the side of the scoop, as at 7. rlhe intermediate portion of the frame J, that is, the bar 5, is disposed above the rocker frames C, when the scoop is in its ordinary loading` position. A link is pivotally engaged with an intermediate portion of the bar 5 by means ofa clevis 9, and is also pivot-ed to an intermediate portion of a lever 10, which is pivoted to an intermediate portion of the handle B, `t 11. The free end of the lever is offset, as at 12, so as to engage the handle A pair of links 13 are pivoted to intermediate portions of arms 6 and extend forwardly there of and are adjustably connected to cross har 141, rry means of nuts 15. 'lhis cross bar 1A normally rests on the draft links lil. The bar 14 is held in engagement with the forward lower portions of the rockers C, when the scoop .is in its loading; position, and the offset portion 12 of the lever 10 is rested on the handle ll. lt is in'ipossihle, when the bar 14 is thus located,- for the scoop to he unloaded, by being.:v upset on the rocker C, since the bar 14% is frictionally engaged with ,the rocker and would rest on the draft links E. By swingingthe lever upward-- ly, so as to disengage the offset portion 12 from the handle B, however, it will be seen that the springs 17 attached to the rockers and the arms 6 will swing` the arms 6 forwardly, thereby moving` the rod 1 -ii out of engagement with the rocker, so that the scoop may be dumped in the usual manner.

A Ouide plate 18 is 'fined to the handle B and to the brace D, so as to be held in parallel spaced relation thereto. The shank 19 of a shoe 20 or the like extends upward` ly between the plate 18 and the handle B. This shank is provided with a series of openings 25. A clamp 21 is engaged with the handle and a bolt 26 passes through one opening` and through the shank 19, s0 that the shank may be held in different adjusted positions in relation to the handle, and thus the loading position of the scoop may be changed as desired.

It is thought that the constructionhoperation, and advantages of the attachment will now be clearly understood, without a more detailed description thereof.

It is apparent that numerous changes in the details of construction, and in the combination and arrangement of parts ,may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A device of the class described wherein a loader includes a scoop, rocker frames on the scoop, a handle extending from the scoop, a draft appliance attached to the scoop, comprising a bar, a pair of links attached to the bar, said bar being located forwardly of the rocker frames and adapted to normally rest on the draft appliance, a pair of arms pivoted to the sides of the scoop, said links being pivoted to intermediate portions of the arms, a member connecting the free end of the arms, and means for moving the member, so as to rock the arms to bring the bars in frictional engagement with the rocker frames.

2. A device of the class described wherein a loader includes a scoop, rocker frames on the scoop, a handle extending from the scoop, a draft appliance attached to the scoop, comprising a bar, a pair of links attached to the bar, said bar being located forwardly of the rocker frames and adapted to normally rest on the draft appliance, a pair of arms pivoted to the sides of the scoop, said links being pivoted to intermediate portions of the arms, a member connecting the free end of the arms, means for moving the member so as to rock the arms to bring the bars in frictional engagement with the rocker frames, and means normally urging the arms fowardly to hold the bar released from the rocker frames. f

3. An attachment for a loader wherein the loader includes a scoop, a handle fixed to the scoop and extending upwardly and rearwardly therefrom, and a brace disposed between the rear end of the scoop and the intermediate portion oft the handle comprising a plate fixed to the handle and to the brace so as to be disposed in parallel spaced relation to the brace, a shank extending between the plate and the handle, a shoe on the bottom end of the shank, and a releasable clamp engaged with the handle and with the shank, for holding the shoe in different adjusted distances from the handle.

In testimony whereof I ax my signature.

PATRICK I-I. JOHNSON.
